Like I said before, I don't know the character, but from everything I read about her she sounded pretty cool. I know at one point I was hearing that she would be back as Spoiler, but then I heard she wasn't. Did they change their minds, or was it never actually confirmed that she was coming back?

i don't read the comics, but what i know is:

She didn't die; it was a fake out by the doctor who treated her. she came back as Spoiler before becoming the 4th or 5th Batgirl (replacing Cassandra Cain) before all this New 52 BS came along and she disappeared.
